Play on your phone or cast directly to your Roku, Chromecast, Apple TV, Fire TV, or other compatible receiver. # Important Castify delivers the original video stream directly to your streaming device. It does not host, modify, convert, or transcode videos. This app is *not* a screen mirroring app. Instead, supported media is streamed directly to your TV for smoother playback and better performance. Castify works best with Roku, Chromecast, and Google Cast devices. Other DLNA-compatible receivers may support a limited feature set depending on the manufacturer. Only websites that provide publicly supported media formats can be cast. Videos that use proprietary playback technologies or unsupported formats cannot be streamed. # Troubleshooting If playback or connection issues occur, they are typically caused by: * Weak Wi-Fi signal * Phone and TV not connected to the same Wi-Fi network * Source website issues * Unsupported media format * Internet connection problems For the best experience, connect your phone and streaming device to the same Wi-Fi network and restart the devices if needed.
